PRIMARY TIME LINE FOR APRIL 20, 1999


From the beginning of the investigation into the shootings at Columbine High School, a timeline was established to record the significant events of April 20, 1999.  The timeline was updated several times as new information became available from all the different sources.  The result is a Primary Timeline, which offers a brief chronological account of the events of April 20, 1999, the movements of Eric Harris and Dylan Klebold, the law enforcement and emergency responses and the media coverage.  This timeline is the basis for a more detailed, comprehensive timeline of the April 20 events that is included in this report.
